Kidney Injuries – very active cells depending on blood for oxygen, nutrients, and removal ofwastes.
3 basic ways to injure the kidneys:
Pre-renal- a condition that has causes primary decreased blood pressure and secondarily decreases GFR and causes kidney failure.example: dehydration, hypotension due to heart failure
Renal – a condition that primarily damages the kidneys and causes kidney failure.example: glomerulonephritis, pyelonephritis, inflammation, toxins.
Post-renal – a condition that has secondarily caused kidney failure due to a primary problem of urine obstruction and subsequent back up into the nephrons.example: kidney stones, ureter tumors, prostate tumors.
